It also heats up the converter quickly on engine startup so conversion of exhaust gases can occur sooner.

Re: A.I.R. Pump
I'm curious as to the mechanism of this heatup... how is it being accomplished? Does the oxygen itself make for more chemical conversion in it and thereby produce heat???
And why are we laughing??? I missed it I guess...
